You can't insert arbitrary shell code inside SQL and expect it to work. Shell code won't be understood inside SQL. No external program can reach back into your shell and set shell variables for you anyway.

The shell already has a special variable to tell you whether the last command failed, and you're already using it: RC=$? ..but you aren't checking it anywhere.

I'm not sure why you're running that command in backticks because you redirect all its output anyway, leaving nothing to capture. You redirect it into several different files, actually. I'm not sure which one it actually ends up in. You need to pick one and only one.

That ending EOF must be at the beginning of the line! If it isn't, your program may malfunction.

You should put RC=$? immediately after running your SQL statement, otherwise the next command may overwrite $? and return a false success.

Try this:

Code:

...

  SQL_LOG_FILE=${LOG_DIR}/${filename}_${LOGDATE}.log
  sqlplus -s <<EOF >> $SQL_LOG_FILE # >> $LOG_FILE
   $USERID
   set serveroutput on size 999999;
   declare
    v_result varchar2(200);
   begin
    bdms_app.pa_bdms_upload_load_rating.upload('$filename');
   exception
    when others then
   end;
/ 
   set serveroutput off;
   exit 0
EOF
  RC=$?
  wait # What are you waiting for?  I see no background commands anyway!

...

   if [ "$RC" -eq 0 ]
   then
           echo "query succeeded"
   else
           echo "query failed"
   fi

capture-schema

capture-schema(1m)					    Application Server Utility						capture-schema(1m)

NAME

       capture-schema -  stores the database metadata (schema) in a file for use in mapping and execution

SYNOPSIS

       capture-schema-dburl url-username name- password password-driver a_jdbc_driver [-schemaname name] [-table tablename]* [-out filename]

       Stores  the  database metadata (schema) in a file. You can also use the Sun Java System Studio IDE to capture the database schema. Run cap-
       ture-schema as the same database user that owns the tables, so that the -username and -schemaname options  are  given  the  same  username.
       Additionally, you can grant the database user running the capture-schema command the ANALYZE ANY TABLE privilege.

OPTIONS

       -dburl		       JDBC URL expected by the driver for accessing a database.

       -username	       user name for authenticating access to a database.

       -password	       password for accessing the selected database.

       -driver		       JDBC driver classname in your CLASSPATH.

       -schemaname	       name of the user schema being captured. If not specified, the default will capture metadata for all tables from all
			       the schemas accessible to this user. Specifying this parameter is highly recommended. If more than  one	schema	is
			       accessible to this user, more than one table with the same name may be captured which will cause problems.

       -table		       name of the table; multiple table names can be specified.

       -out		       output target; defaults to stdout. This parameter corresponds to the schema sub-element of the sun-cmp-mapping ele-
			       ment in the sun-cmp-mapping_1_1.dtd file.

EXAMPLES

       Example 1: Using capture-schema

       capture-schema -dburl jdbc:oracle:thin:@sadbuttrue:1521:ora817
       -schemaname cantiflas -username CANTIFLAS -password enigma -driver
       oracle.jdbc.driver.OracleDriver
